Cuts
Bleeding can usually be stopped by applying pressure to the cut for 2 or 3 minutes. The cut can then be carefully inspected. If it has bled freely any germs will normally have been washed away by the blood.
Apply a plaster dressing firmly, bringing the edges of the cut together so that it knits quickly. Keep dry for 1 to 2 days.
If the cut is deep and the edges cannot be pulled together with a dressing consult the doctor or the practice nurse. A tetanus (破伤风) injection may be needed.
Grazes
Dirt will often enter a graze caused by falling on a hard or rough surface. It must be cleaned out carefully with an antiseptic solution. (消毒液)
After cleaning, leave the graze uncovered. Exposure to the air will cause a scab to form. This will gradually fry and fall off.
It is not a good idea to apply a dressing. This may stick to the graze or make it complete wet and infected.
Bruises
Bruises are very common in children. They normally get better in 7 to 10 days Parents sometimes worry that a bone may be broken, but if in doubt consult the doctor. If a child gets up at once after a fall and moves about normally, it is unlikely that a bone has been broken.
Severe bruising can be treated by: Rest for 24 to 48 hours .In the case of a badly bruised leg, the limb should be raised. Lying in bed is the easiest way to do this.
A bad compress may ease a bad bruise if applied at once. This is made by leaving some material in water and applying it to the bruise.
Insect bites
These are common in the summer .They look like spots about 1/4’’across .They are very itchy (痒) and usually appear on exposed parts, e.g. arms and legs.
The itching can be relieved by calamine lotion (护肤药水).
Burns and scalds
Minor burns and scalds cause redness of the skin. Immediate treatment by pouring cold water over a burn is often helpful. If burns cause the skin severe hot or break the skin, the doctor should be turned to.
Sunburns should, if possible, be prevented by avoiding long exposure and covering exposed areas as much as needed. It may be treated by calamine lotion to relieve the pain.

Trees should only be pruned (修剪) when there is a good and clear reason for doing so and , the number of such reasons is small. Pruning involves the cutting away of overgrown and unwanted branches, and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way.
First, pruning may be done to make sure that trees have desired shape or size. The object may be to get a tree of the right height, and at the same time to help the growth of small side branches, which will thicken its appearance or give it a special shape. Secondly, pruning may be done to make the tree healthier. You may cut out diseased or dead wood, or branches that are rubbing against each other and thus cause wounds. The health of a tree may be encouraged by removing branches that are blocking up the center and so preventing the free movement of air.
One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease , but it is a wound that will heal (愈合). Often there is a race between the healing and the disease as to whether the tree will live or die, so that there is a period when the tree is at risk. It should be the aim of every gardener to reduce that risk of death as far as possible. It is important to make the area, which has been pruned, smooth and clean, for healing will be slowed down by roughness. You should allow the cut surface to dry for a few hours and then paint it with one of the materials available from garden shops produced especially for this purpose. Pruning is usually done in winter , for then you can see the shape of the tree clearly without interference (妨碍) from the leaves and also it is very unlikely that the cuts you make will bleed. If this does happen, it is, of course, impossible to paint them properly .
